H. Power Supply System
(1) Finisher/Saddle Assembly
a. Outline
When the host machine is turned on, it supplies the finisher controller PCB with 24VDC and 5VDC. 24VDC is for the motors and clutches.
24VDC and 5VDC are also supplied as a relay pass drive, 5VDC is used to drive sensors and ICs on PCBs.
If a punch unit (option) is installed, power is also supplied to the punch controller PCB.
Some of 24 VDC used to drive motors is cut off when the joint switch (FJSW), front door switch (FFDDW), or stapler safety switch (FSSSW) is
open.
The block diagram of the power supply system is below.

b. Protective Mechanisms
A circuit breaker (CB1) is monitored to protect the 24 VDC system used to drive the motors against overcurrent. The 24-V system used to drive
the feed motor (FFM), paddle motor (FPM), and stack delivery motor (FAM) is equipped with a fuse which melts in the presence of overcurrent.
